Application filed July 8, 1920. Serial No. 394,854.

To aZZ w from it may concern Be it known that I, Issax SEITZMAN, acitizen of the United States, and a resident of the city of New York,borough of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved Ice-Cream Cutter, oi which the following isa full, clear, and exact description.

This invention relates to improvements in ice cream cutters, an objectof the invention being to provide improved means for simultaneouslycutting a large number of bricks into pieces of uniform or any desiredsizes.

A further object is to provide a machine of the character stated whichmay be operated either by hand power, foot power or engine power. i

A further object is to provide an improved construction of tray in whichthe bricks are supported and out.

A further objectis to provide an ice cream cutter of the characterstated which will not only cut the bricks into pieces of uniform size,but will perform the operation quickly, economically and in a sanitarymanner.

With these and other objects in view the invention consists in certainnovel features of construction, and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings Figure 1 is a view in vertical transversesection illustrating my improved ieecream cutter showing the parts inposition for operation either by hand or'loot power.

Fig.2 is a view in front elevation with the parts as shown in Fig. 1.

Fig. 8 is an end view showing my improved device with the parts arrangedfor power drive, the view being taken in section on the line 3-3 of Fig.2.

Fig. 1 is a view similar to the lower por tion of Fig. 3, illustratingthe clutch controlling mechanism in another position.

Fig. 5 is a view in section on the line 5--'5 of Fig. 4.

Fig. 6 is a view in section on the line 66 of Fig. 4.

Fig. 7 is a plan view illustrating an ice cream supporting tray. 1

1 represents a supporting frame having a table 2 thereon. Along thetable 2 a guide frame 3 is secured and provides mounting for avertically movable plunger 4. drawer or tray 5 is adapted to be movedinto blades 7 are secured to the plunger 1 and are movable through thestripper plate 6 and into the drawer or tray 5 to sever blocks oi icecream, which may be supported in the tray, nto pieces of the desirednumber and size in accordance with the number and arrangement of blades.

The drawer or tray 5 is preferably formed with registering notches S forthe accommodation of notched partitions 9 to separate the bricks of icecream and if desired, individual receptacles 10 having notched walls 11may be located in the tray so that the bricks will be maintained apartand each brick, after being cut into pieces, can be separately removed.

It is obvious that I may construct the trays in various ways and haveany desired number, size and shape thereof so that trays containinguncut bricks can be in readiness for insertion in the machine and thetrays containing the cut bricks can be removed and emptied and returnedafter being supplied with new bricks.

\Vith the machine illustrated I employ several diiterent means foroperating the plunger 4. I provide a standard 12 on the table 2 andpivotally connect to the standard a hand lever 13 engaging the plunger4: so that this lever may be manually operated to force the plungerdownwardly. The plunger 4L is carried by vertically movable side bars 14having tongue and groove guides, as shown at 15, in the frame 3 andextending through the table 2. These side bars 14 are connected by across bar 16, the latter having perforated lugs 17 at its ends.

1 Removable bars 18 are positioned in notches 19 in the sides of frame 1and are perforated, as shown at 20, for the accommo' dation ofvertically positioned rods 21. The upper ends of these rods 21 arebifurcated and pivotally connected to the lugs 17 as shown at 22, andcoiled springs 23 are located around the rods 21 and between the bars'18 and pins 24 on the rods to exert upward pressure on the rods andreturn the plunger f1 to elevated position. Pins 4 25 are positionedthrough the lower porfoot and this lever is connected by a link 28 withthe bar 16 so that the plunger may be depressed by the foot lever ifdesired. A coiled spring-29 connects the foot lever 26 .with the table 2and normally holds the lever in elevated position.

By reason of the construction above described, it will be noted that theplunger 4-can be depressed either by the hand lever 13 or the foot lever26.

hen it is desired to convert the machine into a power driven machine ashaft is supported in the frame 1 and is provided with eccentrics 31having eccentric'straps 32 thereon connected by links 33 with the lugs17 above referred to so that it will be understood that when the machineis to be driven by power, the rods 21 and blocks or bars '18 will bedispensed with and the links 38 connected directly with the lugs 17as'indicated in Fig. 3.

On the shaft 30 a clutch member 3a is secured and is located beside aclutch mem ber 35 which latter is loose on the shaft and is fixed toturn with a drive pulley 36. The clutch members 3%. and 35 are in theform of relatively thick hubs or disks and the clutch member 35 is madewith a ratchet; recess 37 in its inner face in which a spring pressedpin 38 carried by member linormally engages. This pin 88 is of generalangular form and is acconnnodated in a recess 39 in member 34: and acoiled spring all presses the pin toward the member 35 with the outerportion, of the pin projecting beyond the periphery of the clutchmembers and in position to be engaged by a lever 41 pivotally supportedon a pin 43 secured. in frame 1. This lever 41 has a cam face 42 whichis adapted to be engaged by the pin 38 so as to force the pin laterallyout .of the recess 87 and disconnect the clutch.

The lever 41 is provided with a gear segment 4a in mesh with a gearsegment to on the rod 27 so that the movement of the rod 27 by the footlever 26 serves to transmit a pivotal motion to the lever ll to-clevatethe cam endof said lever out of the path of the pin38. i

- By reason of the construction above described,'the operation of thefoot lever 26 causes the lever 41 to be elevated out of the path of thepin 38 allowing said pin to move laterally into clutching engagementwith the member 35, so. that the power transmitted to the pulley 36 willbe transmitted to the shaft 30 to'turn the latter. 'lfhis movement ofthe shaft 30, through the medium of th eccentrics 31 and the links 33,will impa 1'! a downward movement to the plunger 1- to sever the icecream bricks.

When the foot lever 26 is released, the cam lever 41 will movedownwardlv to its normal position in the path of the pin 38 so that asthe shaft 30 completes its revolution the pin 38 will engage the camface -12 and be forced laterally thereby so as to diseooncrz the clutch.

it will thus be noted that with my improved machine, by a simplerearrangement of parts. the plunger may he power (i wlzli l and footcontrolled to cause a single operation at each operation of the loot lver or the power mechanism may be disconnected and the plunger operatedeither by the ha d lever above or the foot lever below.

\Vhile l have described my improved urn chine in connection with theoperation of cutting ice cream blocks into pierc.--. it is obvious thatit might be employed for rutting other goods or material. and hence l donot wish to be limited to the use for r cream only. although this is itsprimary not.

Various slight changes might be made in the general form and arrangementof parts described without departing from the invention, and hence I donot limit myself to the precise details set forth. but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

I claim:

1. An ice cream cutter. comprising a table. a guide frame on the table atray movable in the guide frame, a plunger having vertical movement inthe guide frame. a series of cutting blades on the plunger, a strippemounted in the guide frame above the tray and having slots thereinthrough which the blades of the cutter pass when the cutter is movedvertically, and notched partitions in the tray through which the bladesmove to sever the contents of the tray into separate pieces.

2. An ice cream cutter. comprising a frame, a cutting plunger nu able inthe frame. a. shaft operatively connected to the plunger, a pair ofclutch members on the shaft, a spring pressed pin adapted to loi'li saidclutch members together. a cam IPYOI' normally holding the pin out ofoperative engagement, a rod mounted in the frame. a foot lever on therod. and a pan of gear segments connecting the foot lever and the camlever.

3. In an ice cream cutting machine. the combination with a plunger. ofan ice cream supporting tray having notches therein. notched partitionsin the notches of the tray. notched receptacles adapted to be locatedbeween the partitions and support the bricks of cream to be out. p
